Redmine

I can no longer see a way to configure or remove configured repository for projects in Redmine. At some point I did have it since I have configured the repository settings to go against our Subversion server. Now, we are moving from Subversion to GitLab and want to change the settings but the tab under Project settings is gone

Anyone have this issue? Any suggestions on how to fix it?
